4 Rotor RX7 Screams Around Auto Club Speedway

We all know Mazda’s rotary engine is a marvel of unconventionalness. The 13B is one of the most legendary engines of the 20th century. Defined Autoworks has taken the “If some is good more is better” approach to their RX7. Their RX7 does not have the standard 2 rotors of the 13B, it has 4. The end result is a high revving beast of an engine that sounds like nothing else. So crank up the volume and listen to their creation whip around Auto Club Speedway.
